NAME ^

IOC::Config::XML - An XML Config reader for IOC

SYNOPSIS ^

  use IOC::Config::XML;
  
  my $conf_reader = IOC::Config::XML->new();
  $conf_reader->read('my_ioc_conf.xml');
  
  # now the IOC::Registry singleton is all configured

DESCRIPTION ^

This is the second version of an XML configuration module for IOC. The first version used XML::Simple, which is a great module, but not really the best fit for this. I have now ported this over to use XML::SAX, which is much more flexible solution (not to mention a really nice way to interact with XML). I consider this module to be late-BETA quality (it is currently in production and working without issue for a month now).

METHODS ^

new

Create a new XML::Config::XML object to read a configuration and intialize the IOC::Registry.

read ($source)

Given an XML $source file or string, this will read the XML in it and intialize the IOC::Registry singleton.

TO DO ^

Handle Includes

I thought this will be implemented when I moved to XML::SAX, but it didn't. I am thinking I will try to handle this on my own instead of trying to use XML tricks

Handle Aliasing

This is a minor feature of IOC::Registry, but I want to support it in here eventually. It shouldn't be a problem really, just don't currently have a need to get it in place.

Handle IOC::Proxy objects

It would be nice if you could configure IOC::Proxy objects through XML as well.

BUGS ^

None that I am aware of. Of course, if you find a bug, let me know, and I will be sure to fix it.

CODE COVERAGE ^

I use Devel::Cover to test the code coverage of my tests, see the CODE COVERAGE section of IOC for more information.
